Mets pitcher Johan Santana underwent season-ending shoulder surgery on Tuesday morning, the club announced. The procedure was done at the Hospital for Special Surgery in Manhattan to repair a tear in the capsule in the front of Santana's left shoulder.

The two-time Cy Young Award winner will remain in the hospital overnight, according to the Mets.

Santana, 34, faces extensive rehab after undergoing shoulder surgery for the second time in the last three years. The same injury, which led to surgery in September 2010, cost him 19 months. After missing the entire 2011 season, Santana returned in 2012, though in a diminished state.

Santana highlighted his comeback with his June 1 no-hitter against the Cardinals, the first in Mets history, but his success proved only fleeting. By August, various maladies prompted the Mets to shut him down. His issues lingered into spring training, where the Mets once again shut him down before discovering that he had re-injured his surgically-repaired shoulder.

The Mets owe Santana a guaranteed $31 million in the final season of his contract, which includes a $5.5 million buyout at season's end, though he has likely thrown his last pitch with the organization and perhaps his career.

Still, through his agent, Santana has made public his desire to resume his pitching career.
